1 Claim.

This invention relates to masonry walls of the type built up of preformed blocks and has as an object to provide a wall construction consisting of parallel wall sections provided with a space therebetween, either continuous or broken up into horizontal rows.

Another object of this invention is to provide a wall construction of the character described which is composed of similar individual blocks laid insuperimposed courses and in opposed relationship and having an inner wall formation such that an unbroken serpentine space may be left between the two parallel wall sections.

Another object of this invention is to provide a wall construction of the character described composed of. individual blocks laid in superimposed courses in which the blocks are provided with reinforcing flanges with the flanges on the blocks forming one wall section interposed between those of the other wall section so that a wall of any thickness between predetermined limits may be built up.

A further object of this invention resides in the provision of a wall composed of individual blocks laid as described to form inner and outer wall sections and held together by non-absorbent sheet material laid horizontally and embedded in the mortar.

With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly definedby the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

The accompanying drawing illustrates two complete examples of the physical embodiment of the invention constructed according to the best mode so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a perspective view of a portion of a wall constructed in accordance with this invention;

Figure 2 is a top plan view of part of the wall;

Figure 3 is a view similar to Figure 2, but showing the space between the wall sections filled with insulating material;

Figure 4 is a view similar to Figure 2 showing how the thickness of the wall may be varied;

Figure 5 is a perspective view of one of the individual blocks;

Figure 6 is a perspective view of a section of the sheet material which may be used to tie the wall sections together, and

Figure 7 is a perspective view of a portion of a wall illustrating the use of the sheet material as a tie. 5

Referring now particularly to the accompanying drawing in which like numerals indicate like parts throughout the several views, the numeral 5 designates a wall constructed in accordance with this invention and consisting of two wall sections 6 and I, each composed of a plurality of similar blocks 8 arranged in superimposed rows with the blocks of one row staggered with respect to those of the adjacent row.

Each block has a plurality of vertical equispaced flanges 9 projecting from one face thereof and when the wall is constructed, the blocks are so laid that the flanges 9 on the wall sections 1 and 8 face each other. The distance between the flanges 9 on all of the blocks is the same and is so related to the total length of the block as to permit the blocks comprising the superimposed courses to be laid with all of the flanges 9 in vertical alignment so that the vertical ribs formed by the flanges 9 on one wall section may project into the spaces between the vertical ribs formed by the flanges of the other wall section.

In this manner, a serpentine space is defined between the two wall sections. With the two wall sections 6 and I close together, this space is small, but by spacing the wall sections farther apart, as shown in Figure 4, the spacing between the sections may be increased.

The space between the wall sections may be left empty so that the air space therebetween provides insulation, or as shown in Figure 3, it may be filled with a suitable insulating material [0. In any event, the lack of actual physical contact between the blocks comprising the two Wall sections precludes the transmission of moisture from the outside to the inside of the wall. Lightness is also obtained without the sacrifice of strength which is a very desirable feature as it greatly facilitates the handling of the blocks.

As a modified embodiment of the invention the inner and outer wall sections 6 and I may be tied together as shown in Figure 7, by embedding a sheet material I l in the mortar joining the superimposed rows of blocks as specifically shown in Figure '7. This sheet material I l as more clearly illustrated in Figure 6, consists of a flexible sheet of moisture resisting paper such as tar paper with transverse reinforcing rods l2 held in place by longtitudinally extending wires l3. These transverse rods and longitudinal Wires not only reinforce the sheet material, but also insure a firm bond between it and the mortar.

By embedding this sheet material in the mortar, the inner and outer wall sections are securely held together without the transmission of moisture from the outer to the inner wall section, and the dead air space between the wall sections is broken up into superimposed horizontal rows so as to add to the insulation factor of the wall.

What I claim as my invention is:

A building wall comprising two adjacent wall sections spaced apart and each section being composed of a plurality of similar preformed blocks laid in superimposed courses, each block JOHN T. BLAKE.
